floor of pelvic cavity (limits side-to-side
movement and rotation)

Mammary Glands
Mammary glands as shown are for women in last
trimester of pregnancy or who are nursing. The
areola, a ring of pigmented skin, covers large
sebaceous glands that give it a bumpy appearance.
Sebum reduces chapping and cracking of the
nipple.

Structure of the Testis
Surrounded by the tunica albuginea a tough,
white, fibrous capsule that encloses each
testicle Septa divide each testicle into about
250 lobules Each lobule contains 1-4 highly
coiled seminiferous tubules that give rise to
sperm Interstitial cells lie in between
seminiferous tubules and secrete male sex
hormones

What to do for this lab

• Be sure to look at
• Isolated models for male reproductive system
• Isolated models for female reproductive system
• Include the mammary gland model
